Good morning! Okay. Everybody look at the back of your hand. Bend your wrist so that you know exactly where your arm stops and your hand begins. Got it? I'm going to give you 30 seconds and I want you to count the number of hairs you have on the back of your hand. Okay? Ready, go! (time the children for 30 seconds) How many did you count? (let them give you their numbers) Wow! That's a lot! Now, what if I asked you to count your hand and your arm? What if I asked you to count the hairs on your head? That's a lot of hair!
